Klay would be absolutely phenomenal for ANY team. Unfortunately, he seems very happy with GSW and I think there's virtually a 0% chance he leaves.

If Golden State is hell bent on resigning both KD and Klay (rumor is they are) they will have to dump a contract. The Mavs have the $25 mil trade exception. They could give the Warriors $18.5 mil in cap space by trading Draymond Green for cap space. Basically they would be acquiring Draymond the same way they acquired Andrew Bogut a couple years ago.
